The digits of a German number show its country and shape, and the carrier lookup shows the network it is on now.
Read the digits for the format and the lookup for the carrier. These are Germany's rules from the numbering data.
| What you want to know | What the digits show | What the carrier lookup shows |
|---|---|---|
| Is it a mobile? | A mobile number has 10 to 11 digits after +49, starting 01. | The line type: mobile, landline or VoIP. |
| Which carrier is it with? | The digits give a range of numbers, not a carrier name. | The carrier or network the number is on now, where the network lists one. |
| Where is it from? | The country code +49 is Germany's. | The country, and the region where the record has one. |
A German mobile number is +49 followed by 10 to 11 digits, and the first one is 1.

The +49 and the 0 do the same job, so a number is never written with both.
A carrier lookup for a German number reads the number's format first and then its carrier record.
This is the path one lookup takes. A number can be written correctly and still sit with no carrier name on record, so the result says when the network lists none.
- You enter the numberType it the way it is written at home, such as 01512 3456789, or paste it with +49.
- Its format is checkedEach type of number has its own rules. A mobile needs 10 to 11 digits after +49 and starts with 01 at home.
- Its carrier record is read1Lookup looks the number up in carrier data to find the network that serves it now and its line type.Nothing is sent to the number, so it never rings and its owner is never told.
- You see the carrier and the line typeWith the country and the region, and a note when the network lists no carrier for the number.
A German mobile number has 10 to 11 digits after +49 and starts with 01, so any other length is not a valid mobile.
These lengths come from the numbering data for Germany. German area codes run from two to five digits, so the length of a landline depends on its area code.
| Number type | Starts with at home | Digits after +49 | Written at home |
|---|---|---|---|
| Mobile | 01 | 10 to 11 | 01512 3456789 |
| Landline | 02, 03, 04, 05, 06, 07, 08 or 09 | 5 to 15 | 030 XXXXXXXX |
Three common mistakes make a German number fail the check, and each one is quick to fix.
Keeping the 0 after +49 adds a digit.
The 0 is only for dialing inside Germany, so +49 01512 3456789 is wrong. Drop the 0 and write +49 1512 3456789.
Typing too few or too many digits makes a number invalid.
A mobile number has 10 to 11 digits after +49. With fewer than 10 or more than 11 it cannot be a valid mobile, and inside that range the first digits decide how many are needed, so look for a missing or doubled digit.
Leaving the wrong country selected changes how the number is read.
The lookup reads a number by the rules of the country selected above, so keep Germany selected for a +49 number. Paste a number with its + and country code and the country is read from the number itself.
These are the questions people ask most about carrier lookups for German phone numbers.
How do I find the carrier of a German phone number?
Enter the number in the box above with Germany selected. Type it the way it is written at home, such as 01512 3456789, or with the country code, such as +4915123456789. The free tool returns the carrier or network the number is on now where the network lists one, the line type and the country.
How many digits is a German mobile number?
A mobile number has 10 to 11 digits after +49, starting 01.
Can the first digits of a German number tell me its carrier?
No. The digits help show whether a number is a mobile, since a mobile has 10 to 11 digits after +49, starting 01, but they do not name a carrier. The carrier lookup shows the network a number is on now.
Does the carrier lookup show whether a German number was ported?
Not in the free result. The carrier lookup shows the ported flag for US and Canada numbers only. The free HLR lookup for Germany has a Ported row for a mobile number, and it reads Yes, No or Unknown.
Why does the carrier come back as Not available?
Some numbers, landlines among them, come back with no carrier name because the network does not list one. The line type and the country still show.
Does the carrier lookup show whether a German mobile number is switched on?
No. It names the network and the line type. The free HLR lookup asks the network whether a mobile number is switched on and reachable right now.
Can I look up the carrier of a whole list of German phone numbers?
Yes. This free tool checks one number at a time. A 7-day free trial opens CSV upload and the API, at 1 credit a number.
Does the person know I looked up their number?
No. The lookup reads records only. No call or text goes to the number, so its owner is never told.
You can look up numbers from other countries on their own pages.
